CONDENSING APPARATUS.

Application filed .'iune"9,v1919. Serial No. 302,758.

To aZZ whom it may concem l Be it known that LALEXANDER T. KAsLEY, a citizen of the States, and a resident of Tinicum Township, in the county of Delaware and State of Pennsylvania, have made a new and useful Invention in Qondensing Apparatus, of which the following is a specification.

In mycopending application,- Serial No. 302,259, iledlon the sixth day of June, 1919, and which has matured into Patent No. 1,405,848, Feb. 7, 1922, I have illustrated. a locomotive equipped with' auxiliary power developing apparatus which .is adapted to receive steam exhausted from thelocomotive cylindersv and to expand the steam to a pressure below' atmosphere. The applic-ationv discloses a lo-w ,pressure turbinev receiving steam exhausted from the cylinders of the locomotive and a condenser int-o which the turbine exhausts.

My present invention relates to such auxiliary power developing apparatus and more particularly to the steam condensing apparatus and has for an object to produce new and improved apparatus for cooling the water withdrawn from the condenser.

These and other objects, which will be made apparent throughout the further description of my invention, are attained by means of apparatus embodying the features herein described and illustrated.

In the drawings accompanying and forming a; part hereof, Fig. 1 is a transverse sec tional view of a locomotive tender equipped with apparatus embodying my inventio-n.

Fig. 2 is a fragmental longitudinal view' of a. portionv of the cooling chamber shown in Fig. 1.

Fig; 3 is a diagrammatic longitudinal s ection of a locomotive tender and illustrates a modified form of apparatus embodying my invention.

Fig. 4 is a diagrammatic transverse sectional view of the locomotive tender shown in Fig. 3. l

As illustrated, the locomotive tender is divided into at least two compartments, one in which the condenser and auxiliary power developing apparatus maybe located, and the other in which water withdrawn from the condenser is cooled. A reference to Figs. 3 and 4 will make it apparent that the j tender may be provided with other compartan electric generator 46 turbine drives the generator 6 through the.

ments, namely, compartments for carrying the fuel and water supply.

Referring to Fig. l, the tender shown is provided with a bottom compartment Il in which an auxiliary power developing mechanism including a. low pressure turbine 5 and are mounted. The

agency of a reduction gear 7 and, as described in said copending application, receives steam exhausted from a cylinder or the cylinders of the locomotive. A condenser 8 is also located in the compartment 4 and is adapted to receive steam exhausted from the turbine 5. I have shown the condenser as of the ejector type, but it will be apparent that any desired type capable of being employed in the limited space availcommunicates eJector 8 and abletmay be used. A pump 9 with the discharge port of the is adapted to withdraw water therefrom and deliver it in the form of spray chamber ,10, which is located portion of thetender above ment 4.

As illustrated, the outlet of the pump 9 communicates with a pipeior passage 11 and delivers water through this passage' to a spray pipe. or pipes 12. The pipes 12 are so arranged that they deliver the water in the form of spray to the interior of the cooling chamber 10, the arrangement being such that the spray falls in a more or less uniform mass of separate drops throughout substantially the entire interior vof the cooling chamber. f

'The water is cooled by subjecting the spray falling through the chamber to a current of air. With such an arrangement a relatively large water surface is prevented to the flow of air and consequently a correspondingly large cooling effect is obtained. The air is prferably so admitted to the chamber that the air iow is substantially uniform throughout all parts of the chainber and is also in a substantially countercurrent direction, with relation to the travel ofthe spray through the chamber. As illustrated in Fig. 1, this is accomplished by providing a series of air inlet ports 13 which extends substantially across the tender and from one end to the other thereof and is located intermediate the spray pipes 12 and the bottom of the chamber 10.

to a cooling in the upper the compart- These ports ,13. are: preferably located near.

4 the bottom of the chamber so that the period during which .each particle ofspray 1s sub-s ected to the air low is as' long as possible.,l

` n- Fig. 2, I have diagrammatically shown lathe. arrangement of. the air 4ports113.f".` As

' there illustrated, each portfis in effect the open top'oi:l a trough lwhichnex'tend's transversel across thetender-and' communicates ateac l.end with a passage 15, formed between the4 chamber lO'jjand the ,adjacent i 'y outer wall of the. tender.i Each trough 14 islprovidedwith inclined. side walls sothat each pair of adjacent I troughs for thedeto the bottom of the compartment. '-1

The delivery of air through the' ports 13 is accomplished by employing an exhauster';

ffor the chamber` 10.- As illustrated, the

chamber is .provided with two exhaust-ports ,i `l7 and 18. A combination fan :and separator 19 is so located with relation to these .jminates in 'an upwardly turned discharge ports that it withdraws air from the -chamerand discharges intothe atmosphere. As shown, the fan 19is mountedon a vertical shaft 20 immediately adjacent to the port 17 so that the suctionof the fan communi- Vcates with the port., Apassage -21 communicates with the port 18 and 'is `adapted to deliver air to the opposite side of the fan, so that the .inflow of air lto thel fan from the port 17 is balanced. by the inflow from the port 18. The fan is provided with' an annular discharge passage 22 which terport 23. 1 With this arrangement, the exausting action ofthe fan induces a flow of air through each of the ports 13 and consequently creates a substantially uniform flow throughout that portion of the chamber located above the air inlet ports 13. In order to prevent loss of water which may be mechanically entrained with the air passing through the fan, I have provided the annu'- lar discharge passage 22 and also an annular screen 25 which is located within the `assage adjacent the port 23`and, in effect,- orms lthe outer periphery of the passage 22. This screen is located in the direct line of travel of air discharged from thefan 19,v

Y and while it, to some extent, acts as a baiiie means for drainin I in turning the flow of air upwardly through extends downwardly.. through a cylindrical tube which,.as*shown, ils-secured to the"l i bottom of the .chamber 10 and forms a wai ter tight seal' aroundthe shaft' 20. The shaft is, of course, .provided'withfafj'suitable step bearing and, as shown, n'driven 'by a, turbine 28;.th`roulgh the agency of axreduction gearing 29. .he-gearing 29 may also' drive the pump 9,;'under 'which` conditions .the pumpl 9 would preferably .beglocat'ed below the-shaft 20'.

In order vto prevent'objectionable.swishing of the water collected inthe bottomof the chamber 10, I have. provided 'a series of 16 is formed betweendo'aiiles 31'which, as illustrated,vextend longitudinally ofthe tender and consequently atri-ght angles to the troughs 14.; As illustrated 1n Fig. 2,1 the 'upper portion of each baille 31 is cut out tofreceive theftroughs- 14. lThese baiies may extendto the-tops of the troughs and they ma extend below'the bottomsof the troughs. ith the construction i'11ustrated,it` .will` be. apparent that the troughs themselvescheck.. the tendency' of the water to swish and l'also 17o-splash as a result of quickystops and starts of the tender, whereas the baffles'l willftendto prevent swishing due to the rolling motion of the tender.l The chamber 10 is shownv provided with a water delivery port 32,`

which communicate'swit'h the intake ofthe condenserSthI-oughapipe 33.. j

- In operationthe fan creates a current of air through the interior of thefchamber V10.

The vacuum'withinthe condenser occasions i 100 a flow of water at a relatively highve'locity through thepipe 33'a-nd into the condenser 8. This water is withdrawn from-thecondenser by means vof thev p11-mp9 which, with the type of condenser illustrated,'also rwithdraws the air -or non-condensable fluids from the condenser and discharges. them with the water into- `the chamber 10. The water entering the chamber 1 0 is broken into a mass of separate dropsl or sprayl and falls through the chamber, where it is .subjected to the air. flow induced bythefa-n. 19. The

arrangement `of the ports l13 in conjunction with the-flow of air issuing from these. ports is sueha's'to deiiect the separate particles of water tending'toenter the air ports and to cause all ofthe water-to'pass through theconverging passage 16 into'thebottom of the. chamber 10.

In Figs. 3 and 1 1, I have shown modified arrangement of the apparatus'. embodying my invention.- As illustrated, lthe tenderv is dividedinto a fuel carryingcompartment 35, two water compartments '36, a cooling 'chamber 37 and a compartment 38 vin which an auxiliary.- power developing .mechanism including -a turbine 39, a gearing 40; andan electric generator 41 are mounted'. The'turbine 39 receives low 'pressure steam through a conduit or passage 42, andthe steam exhausted from the turbine is delivered to a condenser 43, which is also located in the compartment 38.

or pipes 46. Thesepipes 46 are shown lo- `out theentire chamber.

cated across a portion of the top of the chamber 37 `and are so arranged that substantially the entire chamber is lled with the water spray delivered by them. The'- located near the bottom of said chamber and so distributed as to create a substantially uniform flow of air, throughout substantially allportions of said cooling chamber and in a substantially countercurrent 'flow relatively to the direction of travel of the spray through said chamber, and a fan for withdrawing air from said chamber and thereby vinducing a flow through said air delivery ports. Y 2. In combination with the tender of a locomotive, an auxiliary power developing chamber isillustrated as provided with air \mechanism' for the locomotive, mounted on discharge ports 47 arranged to occasion a more or less uniform ow ranged with relation tothese ports in a manner described in connection with Fig. 1, and is adapted to perform the double function of withdrawing air from the chamber and `also separating the entrained water from the air so withdrawn. As shown, air inlet ports 50 are provided in the rear wall of the chamber and are so arranged as to produce a substantially uniform iow of air throughout the entire chamber. This flow is also in substantially the direction of a countercurrent with relation lto the travel. of spray through the chamber, since its general direction of flow is upward toward the ports 47, whereas the general direction of low of the spray is downward. It will, of cou-rse, be apparent that the inrushing air defiects the How of water so that the spray will flow at an angle .to the vertical in passing through the chamber. As illustrated, baflies 51 are provided along the inclined wall of the chamber for preventing undue swishing of the water and also for preventing the water entering the fan 48, in case of an emergency or other quick stop. The water collects inthe bottom of the chamber and is delivered by a passage 52 to the condenser 43. It will, of course, be apparent that `a l by the appended claims.
